Requirements for building USRP2 FPGA firmware on Ubuntu 10.04

Hi,
I know its been discussed many times, it’s a bit confusing as to
the exact versions of the tools that are required for building USRP2
FPGA firmware, for use with the UHD driver on Ubuntu 10.04. The README
file in the uhd git repo for the fpga folder doesn’t list this
information.

Question 01: Which version of ISE is know to work with the UHD driver
and GNU Radio 3.3.1 master branch?

Question 02: What is the build command and what options should I use to
build the USRP2 UHD FPGA firmware image?

I think there is a terminology issue here. The FPGA image is built by
ISE. The firmware is built by gcc. I assume you mean the FPGA image.

This is where you are going wrong. UHD is not a part of GNU Radio
3.3.1.

If you want to use UHD, you need the GNU Radio next branch. In that
case you must use ISE 12.1.

Question 02: What is the build command and what options should I use
to build the USRP2 UHD FPGA firmware image?

Go into the u2_rev3 directory and type “make bin”

Hi Matt,
Thanks for the reply.

Could you tell me a bit more about the firmware component? I’m just
trying to figure out how to build the files that go into the SD Card.

The FPGA image is one, but I wasn’t aware there is an additional
firmware component.

Best regards,
